POLYMER THIN-FILM, PROCESS FOR PRODUCING PATTERNED SUBSTRATE, MATTER WITH PATTERN TRANSFERRED, AND PATTERNING MEDIUM FOR MAGNETIC RECORDING

摘要

A polymer thin film 30 includes a continuous phase 10 primarily composed of polymers of a first monomer 11 and cylindrical microdomains each of which is primarily composed of a polymer of a second monomer 21, the cylindrical microdomains 20 being distributed in the continuous phase 10 and oriented along the penetration direction through the film, wherein the polymer thin film 30 contains block copolymers 31 which include at least respective first segments 12 formed by polymerization of the first monomer 11 and respective second segments 22 formed by polymerization of the second monomer 21, and polymers 13 compatible with the first segments.
